摘要
目的探讨超声和核磁共振对胎盘植入的诊断价值。方法回顾性分析122例前置胎盘孕妇的产前超声、核磁共振影像资料,根据剖宫产术中所见或术后病理将其分为胎盘植入组(100例)或非胎盘植入组(22例),分析超声和核磁共振对胎盘植入的诊断价值。结果超声诊断胎盘植入的灵敏度(54.00%)和诊断符合率(59.02%)低于核磁共振诊断的灵敏度(84.00%)和诊断符合率(85.25%),差异有统计学意义(均P<0.05)。超声诊断胎盘植入的特异度为81.82%,与核磁共振(90.91%)比较,差异无统计学意义(P>0.05)。结论超声是产前诊断胎盘植入的首选方法,核磁共振可作为重要的补充检查方法。
Objective To explore the diagnosis value of ultrasonography and magnetic resonance imaging(MRI)of placenta accreta.Methods Prenatal ultrasonography and MRI data of 122 pregnant women with placenta previa were retrospectively reviewed.According to the results of cesarean section or pathology,they were divided into placenta accreta group(100 cases)or without placenta accreta group(22 cases).The diagnostic value of ultrasonography and MRI in placenta accreta was analyzed.Results The sensitivity and coincidence rate of ultrasonography were 54.00%and 59.02%respectively,lower than MRI(84.00%,85.25%),and the differences were statistically significant(P<0.05).The specificity of ultrasonography was 81.82%,which was not significantly different from the specificity of MRI(90.91%)(P>0.05).Conclusion Ultrasonography is a method for screening for placenta accreta,and MRI can be used as an important supplementary examination method of placenta accreta.
